All members of TF77, which launched airstrikes on Pyongyang and Haeju on 3 July 1950. USS Rochester (Optatus model) and HMS Belfast (Neptun) were the support force, and HMS Triumph (Neptun) and USS Valley Forge (wish I had one) delivered the airstrikes. A large part of the North Korean air force was eliminated, and the presence of F9F Panther jets probably dissuaded the Russians and Chinese from providing additional outclassed prop planes as replacements.
